Using the microset of satellite data included with the lesson to investigate surface characteristics, students will apply percentage to determine ... Full description.

Corals feed on algae that thrive in the sunlit water surrounding a reef. However, when water temperatures get too warm, the algae food source dies and corals turn a whitish color. Through scientific observation, it has been determined that coral bleaching may occur when sea surface temperature (SST) exceeds 30C or 86F for a week or longer. During late 2005, a major coral bleaching event occurred when ... Full description.
